Supernumerary chromosome 1 in interphase nuclei of atypical germ cells in paraffin-embedded human seminiferous tubules.
The so-called atypical germ cells or cells of carcinoma in situ morphologically resemble neoplastic cells in seminoma. Since seminomas show numerical aberrations of chromosome 1 we have used a DNA probe specific for chromosome region 1q12 to determine whether such aberrations can be detected in atypical germ cell nuclei in paraffin-embedded seminiferous tubules as well. One-third of intratubular nuclei, containing atypical germ cells, consistently showed three hybridization signals in contrast to two signals regularly observed in normal intestine and in spermatogonia. We thus show that cytogenetic studies of precancerous cells can be performed directly on the tissue where these cells originate.

[Pathologic Papanicolaou class IV smear without histologic correlation--what should be done?].
13 of 188 patients with a Papanicolaou smear Type IV of the cervix showed histologically only abnormal epithelium, CIN I or II, a result which does not explain the cytologic result. For several reasons a hysterectomy was performed in 5 cases. In only one of these patients a pathological finding, an endometrial carcinoma stage 0, was detected. In the other 8 cases a routine procedure under regular colposcopic and cytologic control had been performed. According to the results during a median follow-up over 52 months, such routine procedure is justified, if the patient wants children and if respectively a regular colposcopic/cytologic control or a control curettage after 3-6 months is undertaken.

[Adenocarcinoma of the cervix in Peutz-Jeghers syndrome. Case report and review of the literature].
The incidental finding of "adenoma malignum" or minimal deviation adenocarcinoma (MDA) of the cervix in a 38-year-old woman with Peutz-Jeghers syndrome (PJS) is reported and the literature is discussed. This highly differentiated form of adenocarcinoma is extremely rare but, like some other rare neoplasms, may occur more frequently in patients with PJS syndrome. Since the prognosis of MDA is considered poor and the histological diagnosis is often missed on biopsy, the importance of closely correlating clinical and pathological findings is emphasized.

[Fabry's disease. Light and electron microscopic cardiac findings 12 years after successful kidney transplantation].
Fabry's disease (angiokeratoma corporis diffusum universale) is a disorder of sphingolipid metabolism affecting predominantly male patients. Renal damage is usually the cause of death in the fourth or fifth decade. Renal transplantation represents a new approach to correction of uremia and perhaps even of the basic congenital metabolic anomaly. In this case the patient, a 57-year-old man, developed renal failure at the age of 45 and received a renal allograft at that age. The transplantation was followed by complete remission of uremia and concomitant symptoms, but later complicated by progressive cardiac failure, anginal chest pain and arrythmia. Necropsy findings showed persistent deposition of ceramide in the myocardium and especially in the conduction system. This was documented, for the first time to the author's knowledge, by electron microscopic investigations. Cardiac manifestations of Fabry's disease are discussed in relation to patients with renal transplants.

P53 mutations and loss of heterozygosity on chromosomes 8p, 16q, 17p, and 18q are confined to advanced prostate cancer.
We analysed 39 prostatic carcinomas for loss of heterozygosity on chromosomal arms 8p, 10q, 16q, 17p and 18q and for mutations in the p53 anti-oncogene. Loss of heterozygosity (LOH) on 8p was detected in one out of 5 informative tumors, LOH on 16q in 3 out of 21 tumors, LOH on 17p in 2 out of 18 tumors, and LOH on 18q in 2 out of 17 tumors. No deletions were observed on 10q in 14 informative tumors. p53 alterations occurred in 3 out of 38 examined tumors, comprising two point mutations and a small deletion. Chromosomal deletions and p53 mutations were confined to locally invasive prostatic carcinomas, suggesting that they are associated with the progression of some prostate cancers rather than with tumor initiation.
